Abstract
Oppfinnelsen angår et oppdelende holografisk spektro- meter (12) for analyse av strålingen fra en Infrarød kilde (16). Det holograflske spektrometer (12) omfatter en plezoelektrlsk blokk (40) med en holograf- isk linse (38) på en side, en sats med detektorer (36) på en annen side og et par flnstlllbare elektroder (32, ¿ 34) på motstående sider. Stråling fra kilden (16) som faller Inn på den holograflske linse (38) blir delt opp l komponentbølgelengder (44, 46) og rettet mot detektorsatsen (38). Den holografiske linse (36) har et opptegnet holografisk interferensmønster slik at stråling fra på forhånd bestemte bølgelengdekoraponenter blir adskilt tilstrekkelig til at stråling av forskjel- lige bølgelengder faller på forskjellige detektorele- menter (48) l detektorsatsen (36). Ved påtrykning av en spenning på elektrodene (32, 38) skapes det et elektrisk felt l den piezoelektriske blokk (40) slik at den enten trekker seg sammen eller utvider seg. Denne forandring i den piezoelektriske blokk (40) endrer retningen på strålingen fra den holograflske linse (38) mot detektorsatsen (36). På denne måte kan mistllpas- nlng mellom kilden (16) og den holografiske linse (38) utllgnes ved at den piezoelektriske Justering av blokken (40) vil føre til at stråling med de enkeltvise bølgelengder faller på det ønskede detektorelement (48). Vider kan stråling med forskjellige bølgelengder rettes fra et detektorelement til et annet. Detektor- satsen (36) er selvavsøkende slik at et absorbsjons- 1 spektrum kan måles og registreres over et frekvens- : område.
